Question

What is the volume of a cone that has a diameter of 4.5 and height of 6 5/8

Answer 1

V={h(3.14...)r^2} / 3
h=6 5/8 or 6.625
r=4.5/2=2.25

plug it in:
{6.625 (3.14.....)[2.25]^2} / 3
={6.625 (3.14.....) 5.0625} / 3
=105.3660724 / 3
=35.12202412

(wasn’t sure what place you were supposed to round to, but V=35 unit^3)
